When I put it on the battery, the two leds light up immediately and I can't change the control voltage through the trimpot. I saw in some other images on the internet of this same scheme that instead of the 8volt zener diode they use an 11v one. Anyway, a question is if you set it up and got it to work.

Quando o coloco ligado a bateria os dois leds acendem de imediato e não consigo mudar a tensão de controle através do trimpot. Vi em algumas outras imagens da internet desse mesmo esquema que no lugar do diodo zener de 8volts usam um de 11v. Enfim, a pergunta é se vc montou e conseguiu que ele funcione.
